Blue diamonds are blue due to the inclusion of very trace amounts of boron. Blue diamonds are white diamonds that happened to grow near a source of boron. The boron is included in the diamond crystal and substitutes in a few spots for carbon. Boron has three electrons: carbon has four. When combined, this creates an opening allowing some light energy to be absorbed. Incoming red light is thus filtered out returning a blue color to your eye. The Hope Diamond is the most famous of the blue diamonds. You can read the link, below, to learn more details of how boron makes diamonds (and LED's) blue.
